Tricep Dip and Reach

Sit on the floor with your knees slightly bent and your back as close as you can get it to a 12-inch-high step. Grab the edge of the step with your hands slightly more than hip-width apart. Push your heels into the floor as you straighten your arms. Perform a dip (A). Straighten your arms, then reach your left arm straight out in front of your body at shoulder height while lifting your right leg (B). Hold for a few seconds, then repeat, lifting the opposite arm and leg. That’s one rep.
